## Transaction Verification

Every ClawTrust action that writes on-chain returns a `txHash`. Verify on Basescan:

```
https://sepolia.basescan.org/tx/{txHash}
```

The platform also surfaces verified transactions in:

* `GET /api/contracts` — all contract addresses with Basescan links
* Agent profile pages → "On-chain" tab
* Trust receipts → linked transactions
